Red Hat is a business, and made a simple business decision. Maintaining Xen support would have meant maintaining a very large set of patches. They made the decision that the effort (and money) needed to maintain Xen outside of the mainline kernel was not worth it.
Perhaps a silly question, but why maintain patches ? Why not compile a new version and discard all the patches ? Patches are a messy manner to maintain programmes.
That's the form they come from the community in. You'd have to ask the devs for details.
KVM was not chosen over Xen so much as KVM was a much less expensive hypervisor to support. As for it being mature or not; Well, put on your kevlar pants because that is a matter of opinion.
Which is better on C5 and C6 ?
For what? That is a loaded question.
For me, I use C5 + Xen when I am backing *nix VMs and c6 + KVM when backing MS VMs as the PV drivers for windws are less than ideal.
As a follow-up, Xen dom0 support began getting into the mainline kernel at 2.6.33 (EL6 is based on 2.6.32). It is very likely that we will see Xen dom0 support returned in the next major release.
In about 4 or 5 years ??? :-)
They tend to release a new x-stream release every three years. EL6 is a year old, so I'd bet in two more years we will see EL7 and that both KVM and Xen will be supported.
